CORRECTED(OFFICIAL)-UPDATE 1-Enbridge shuts N Dakota oil line after another leak found

(Company corrects day to Tuesday in first bullet point and
second paragraph)

* 210,000 bpd line closed Tuesday after leak found

* Second shutdown in less than a week

* Company estimates 2 barrels leaked

* No estimate yet for restart

CALGARY, Alberta, May 7 (Reuters) - Enbridge Inc,
Canada's largest pipeline operator, said it shut its 210,000
barrel-per-day North Dakota pipeline for the second time in less
than a week after finding contaminated soil during integrity
checks.

Graham White, a spokesman for the company, said in an email
the line was shut on Tuesday after the discovery near Grand
Forks, North Dakota. The company does not yet know when it will
restart. Enbridge estimates 2 barrels of oil leaked from the
line.

The shutdown follows a similar incident last week on the
pipeline, which serves producers in the Bakken oil field. The
line was shut for two days after checks discovered a barrel of
crude had leaked into the ground from the pipe.

Enbridge says the two oil leaks were not related.

The leak is much smaller than some prior incidents on
Enbridge's U.S. pipeline network. In 2010, its Line 6B ruptured
near Kalamazoo, Michigan, spilling 20,500 barrels of crude into
a waterway, the costliest onshore oil spill in U.S. history.
